MOUNTING-commit.

Specication of Letters Patent.

Patented Dec. 23, 1919.

Application led July 14, 1919. Serial No. 310,851.

To all 'whom t may concern.'

Be it knownthat I,YLEsTER S. ItiLEY, a citizen of the United States,residing at Greenwood, county of Middlesex, Commonwealth ofMassachusetts, have invented certain new and useful Improvements inMounting-Corners, of. which the following is a specification.

In the mounting of lphotogrziphapostcards and the like, whether inalbums or on other surfaces, it has been proven highly desirable to havethe print yet rmly without that finality which mounting by means ofpaste renders unavoidable. Corner mounting has proven to be a verysatisfactory manner of effecting this result and various systems anddevices v'have been provided for holding 'the print forming andself-attaching making them b' the corner.

The problem of providing an artistic and effective mount in a simple andcommercial form is not simple as the requirements are varied andpractical difficulties attend each requirement.

The object of my present ,invention is to provide corner mounts whichwill fulfil a maximum number of these requirements with a minimum ofdiiliculty and all at a low cost, making the articlepracticallyavailable for general use.

The advantages eected by` my 'invention ,are briefly as follows:

By it I provide individual corner pockets upon any partof a page ormount.` Their utility is therefore general as they may be attached toany surface without previous preparation of it as a mount. The devicesin accordance with my invention' may be produced from ready gummedstock, being so devised that in folding they become selfl.complete unitsand permanent fixtures..

In accordance y with my invention it is l also possible to produce theseunits in group sets so that they may be conveniently han dled and sothat sets in varied colors may be had without .confusion and withoutdelay u incident to sorting.

These and various g prominently characteristic of my invention. Asillustrative of it I have shown in the accompanying drawings havefoundhighly successful for practical use and which I will describe indetail in held lightly and it is not intended "other features areV visstruck from glued a form which I II a plan view of a corner unit. Fig.III a group set of units.

Fig. IV an indicated section on the linev IV-IV, Fig. II. v

Fig. V- an enlarged section through corner on the line V-V, Fig. I, and

Fig. VI a general view of a corner folded. Referring now to the cornerunit herein employed as illustrative of my invention, it will be seenby-reference to Fig. II that each corner unit consists of a flat paperstamping `comprising a'somewhat V-shaped exposed section 1. Theshape isgenerally that of a right triangle being notched or cut out at 2.

On the equilateral sides of the piece 1 I form two flaps, one apreferably square Hap indicated at '3 and the other a triangular flapindicated at 4. The triangular flap is preferably similar to the section1 except that it is not notched or cut out. The ap 3 is referablyy twicethe area of the flap 4:, the ap 4 being really the triangular half ofthe area 'divided on its diagonal.

The flap 3-is also scored lightly at d, e I

leaving an area 31 as indicated in Fig. VI to bring a small area ofgummed surface next to the'back of the mount or photograph P where it isdewhich may be folded back sired to give some permanence of attache.y

ment between the corner and the print. This -is sometimes desirablewhere the corners are folded on'the print first orwhere to remove theprint. vIt may be here noted that while the flaplaffords considerablepermanencyof attach- 'ment so that the print or photograph is not easilydislodged from the corner, itis still possible without destroying thephotograph to peel it loose from the corner 31 by drawing back thecorner of the print which thus rolling strips ofi' the gummed corner 31with the practical certainty that the print be destroyed or in iure lasshown in Fig. II stock and may be" considered `as lying in Fig. IIlgumined side up. The upper surface of the flaps 3 and 4l are thereforegumined surfaces. The sur face of the corner or exposed portion 1 wasoriginally a gummed surface but .in striking The corner blank out theseblanks I preferably print the surture of its gumming so that the surfaceis v necessary to ma VISIS no longer sticky and will not attach to anopposite page in case an album is used.

also preferably embossed making the exposed portion highly attractiveand adding to it considerable rigidity and decreasing possibility oftearing when the corner of the print is inserted.

Eachv corner unit is preferably scored along the lines -b, b -e, and thesection 31 is also scored along the line 2l-e. This permits the cornersto be folded with rapidity and certainty.

In folding the flap 3 is 'preferably folded first and the ila 4 turnedover it as indicated in Fig.'l Where it is desired to simply stick thecorner on the mount and then insert the e one moistening of' the flapsthus folded inasmuch as the surface of the flap 4 only covers half ofthe surface of the flap 3. y

Where itis desired to attach the corner to the print the contactingsurfaces of the flap 4 and the flap unlted giving the form w ich may bedesired.

As heretofore sort are used in different colors, l itis important thatthese sets be kept together to avoid the necessity of sortmg and to giveconvenience in handling.

In accordance with my inventionI am able to produce my corner in setgroups as indicated in Fig. III. It will be noted that this set group isa rectangular group from which only four small notches are struck out aswaste. A' group may therefore be produced from a continuous strip of theproper width. ,In order that thf'corner units may be readily detachableand yet that the group as a whole may remain together I partially severthe set blank into its corner units alon the lines of demarcation of.the unit b anks which I have indicated in Fig. ted line, asdistinguished from the dotted and dash line whlch indicates the line offold at a-b, b-c, d-e. This line of semidetachment may readily be tracedin Fig. III, being practically four right angular arms radiating fromthe center in the form of the well known swastika symbol.

, While I do not limit myself to the particular form of corner shown or'to theparticular s et group, it will be appreciated that corner thepermanenrl utillzecl afterward as pointed out articles of this setsusually of four. Where The corner 1 in additionto the printing isl rintafterward it is onlyv 3 may be permanently designs and effects are usedIII, by dotp the other.

l/Vhile I have shown and particularly de scribed in this applicationthis highly developed form with its various advantages above explained,I am not to be understood as limiting myself to any one of the speciic'features or combinations of features thus described except ashereinafterward defined by my claims.

What I therefore claim and desire to se4 cure by Letters Patent is:

1. An article and a triangular flap foldably attached to of the classdescribed comprismg a corner piece, a rectangular Hap the marginsthereof, said flaps having gummed backs.

',2. An article of the class described comprismg a corner piece ofsubstantially triangular shape, a rectangular flap and a triangular iapfoldably attached to the margms thereof, said iiaps having gummed backs.

3. An article of the class described comprising a substantially V-shapedcorner p1ece,a rectangular iiap and a triangular Hap foldably attachedto the margins thereof, said flaps having gummed backs.

An article of the class described comprising a flat blank gummed on theback and-including an exposed part and foldable iiapl parts, the gummedsurface of the exposed part being printed whereby the exposed surfaceisrendered non-adhesive.

5. An article of the class described comprising a -fiat vblank gummed onthe back and including an exposed part and foldable flap parts', t egummed surface of the exposed part being treated to^render itnonadhesive.

6. An article of the class described comprising a flat blank gummed onthe rback and including a substantially triangular front part, andfoldable flaps, the gummed surface of the front non-adhesive by printmarticle of manufacture consisting of a blank containing 'a set ofdetachable units, each part being rendered one-fourth the area-of thecomprising a front area and a palr of flap areas, saidunits beingpartially blank, said units being partially severed.

from each other in the blank group.

9. An article of manufacture consisting of a substantially rectangularblank containing a set of units, each comprising a rectangular area anda pair of triangular areas each of one-half the area of the square, saidunits being partially severed from each other in the blank group.

10. A mount of the class described, comprising a c orner receivingpocket, and a fold- -able portion having a gummed surface adapted to `bedisposed outwardly for attachment to the article to be mounted.

11. As a new article of manufacture and sale, a gummed sheet scoredalong predetermined lines of severance to produce alurality of similarcorner receiving po ets for mounting a photograph or the like.

12. A series of detachable mounts for a photograph or the like, formedfrom a sheet of material gummed on one face, said mounts being partlysevered each from the other in said sheet.
